Optical sensors are used in a multitude of applications ranging from industrial and manufacturing to medical and consumer markets. One particular type of optical sensor is the E3S-R2E43 Photoelectric Sensor, which is designed for both indoor and outdoor use. It is a versatile and reliable high-performance photoelectric sensor with an integrated light source.

The E3S-R2E43 Photoelectric Sensor is a high-performance, compact, and low-cost photoelectric sensor with integrated light source, using a combination of pulsed infrared LED and PNPN-type phototransistor output structures to realize high-speed and precise response. The sensing range covers from 4m to 10m in maximum, and the switching distance can be adjusted within this range.

The E3S-R2E43 Photoelectric Sensor has a high degree of stability and reliability, along with a robust and ergonomic design for quick and easy installation. It is equipped with hysteresis control circuits, providing automatically controlled light sources that prevent oscillation and shorten response time. The output response time is about 0.3ms and can be adjusted to meet different needs. In addition, the sensor features an aluminum cover to help protect against dust and liquids, meeting protection class IP67.

The E3S-R2E43 Photoelectric Sensor is suitable for a wide variety of applications, such as industrial automation, robotics, medical equipment, security systems, and other applications that require accurate sensing at far distances. This highly precise optical sensor can detect even the smallest objects with the maximum sensing range of 10m and resolution rate of 0.1mm.

The working principle of the E3S-R2E43 Photoelectric Sensor can be divided into the following three main components: the light-emitting diode (LED), the photodetector, and the optical detection circuit.

The light-emitting diode (LED) is used to emit a short pulse of light over the sensing range. Once this light pulse strikes the target object, it is reflected back to the sensor, and the photodetector detects this reflected light. The signal detected by the photodetector is then passed through an optical detection circuit, specifically designed to detect this signal and convert it into an electrical output.

Once this electrical signal is amplified, the photoelectric sensor can detect and calculate objects within its sensing range. The output response time is determined by the type of photodetector used and the amount of current used to drive the circuit.

The E3S-R2E43 Photoelectric Sensor is a versatile and reliable high-performance photoelectric sensor with an integrated light source and suitable for a variety of applications. It offers a high level of stability and reliability, with a robust and ergonomic design for easy installation. Its accuracy and response time make it suitable for a wide range of industrial and automated applications, providing precise and reliable results.
